Efficacy, Safety and Pharmacokinetic of ArtequinTM P. Falciparum Malaria

January 23, 2013 updated by: Albert Schweitzer Hospital

Open-label, Stratified Study on the Efficacy, Safety and Pharmacokinetic Characteristics of Two Paediatric Formulations of ArtequinTM in Children With Acute Uncomplicated P. Falciparum Malaria

Treatment of Plasmodium falciparum malaria in Africa is increasingly difficult. Resistance to cheap efficient antimalarial drugs poses an increasing threat. The rapid emergence of resistance to sulfadoxine - pyrimethamine, already seen in East Africa is growing and is likely to have an striking impact on mortality in many other African regions where no obvious alternatives are available. WHO recommends the use of drug combinations containing artemisinin compounds, i.e., artemisinin-based combination therapies (ACT). Previous clinical trials have shown that the combination of artesunate with mefloquine is highly effective and well tolerated in the treatment of multidrug-resistant falciparum malaria, retaining the benefit of rapidity of action while augmenting cure rates, and apparently slowing the development of mefloquine resistance. Compliance with sequential combination regimen of antimalarial drugs is notoriously poor. Therefore, in order to limit the development of resistance to both drugs and ameliorate patients' compliance to antimalarial treatments, an optimal simultaneous combination regimen of artesunate and mefloquine in a practical single blister pack has been developed by Mepha Ltd. and successfully tested.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Artequin dosages could only be tested in children able to swallow tablets and with a body weight of more than 20 kg. However, there is a great need for an Artequin formulation for smaller children unable to swallow tablets. The new Artequin Paediatric oral formulation is a flavoured, taste-masked preparation of granules of 50 mg artesunate and 125 mg mefloquine as a fixed-dose combination (once daily in one single Stickpack, i.e. 3 Stickpacks for a 3-day treatment). It is suitable for children with up to 20 kg body weight (with a range of 10-20 kg).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Efficacy, Proportion of patients cured on day 28

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Efficacy: day 14v cure rate, parasite and fever clearance time, parasite reduction rate, gametocytemia, in relation to blood concentrations of Dihydroartemisinin and mefloquine, safety, tolerability, acceptability
parasite and fever clearance time, parasite reduction rate, gametocytemia, in relation to blood concentrations of Dihydroartemisinin
Time to complete clearance of fever and parasitemia Assessment in relation to DHA and mefloquine blood levels
